To all whom it 'may concern.'

Be it known that l, GEORGE C. DEBAY, a citizen of the United States, and resident of Cheswick, in the county of Allegheny and State of Pennsylvania, have invented a new and useful lmprovement in Glass-Manipulating Apparatus; and I do hereby declare the following to be a full, clear, and `exact description thereof.

My invention relates to glassimanipulating apparatus.

ln the manufacture of window-glass, the glass is first formed in the form of cylinders, which are cut longitudinally and the cylinder'is then opened out'land flattened. rlhis last operation has heretofore been performed by hand, and involved the employment of skilled labor, while, furthermore, the operation was a long and tedious one.

The object of my invention is to provide aparatus by means of which the opening out and flattening of these glass cylinders may be accomplished in such a manner as to greatly reduce the time and labor, while at thev same time the product will be of-a stand-V ard anduniforin character.

To these ends my invention comprises the novel features hereinafter set forth and claimed. Y l

In the accompanying drawings, Figure 1 is a sectional plan view of a furnace with my apparatus installed therein; Fig. 2 is an enlarged frontview of my improved apparatus with a portion ofthe furnace; Fig. Sis a section on the line 3-3, Fig. 2; Fig. @is a section on the line 1-4, Fig. 2; Fig. 5 is a vertical section of the receiving chamberfor the cylinder with the preliminary device -in position therein; Fig. 6 is a front view of the preliminary device; Fig. 7 is al section of the final attening device; Fig. 8 is a sectional view of the preliminary device; and Fig. 9 is a front view of the handlesof the preliminary device and the method of locking the same together.

Referring to the drawings; I have illus` trated my invention in connection with a furnace of circular form, with a series of carriages traveling on a track therein, each carriage carrying a flattening stone or plate.

The numeral 2 designates the outside circular wall of the furnace and 3 the inside circular wall, leaving the circular open space 4 at the center.` Within the furnace is the circular track 5V uponv `which the' n'fheelsvr of the carriage 7 travel. These carriages may be of any suitable construction, and said carriages carrythe flattening stones S of the ordinary character. 1n order to drive the carriages '7, a rack-bar 9 is provided which may be engaged by suitable power* driven cog-wheel for moving said carriages intermittently; as hereinafter set forth.

A vestibule 10 communicates with the furnace, said vestibule having the charging f opening 11 through which the glass cylinders are introduced. rlhis vestibule 10 has the opening 12 which connects with the opening 13 of the furnace.

ri pedestal 14; forms a support for the casting 15. llihis casting has the projection .16 which fits into an opening in said pedestal. i washer 17 is interposed between said pedestal and said projection, and a screw 18 is threaded into said projection, whereby said castingl is swiveled in said pedestal. The casting 15 has an opening 15a extending through it to receive the outer end of the beam 19. The beam 19 has the opening 2O through which the pin 21 passes, said pin being threaded into the casting 15 as clearly indicated in Fig. 5. To allow for slight tilting of the beam 19 the` casting 15 is cut away at22 and 23. rEhe inner end of the beam 19 has the downwardly projecting arm 2-1 provided with the roller which moves on Vthe track 2G. This track 26. as indicated in Fig. 6 is at a lower level at one end as at 27 for the purpose more fully hereinafter set forth.

Mounted on the beam 19 and slidable thereon are the bearings 28. rFliese bearings have the lugs 29 to which are pivoted curved arms 30. Hinged or pivoted to the arms 30 are like curved arms 31 which are pivoted to the lugs V32 on the divided halves 3B of the spindle 34. At the outer end of each half of the spindle 31 are the handles The latch 36 is adapted to lock the spindle in closed position, as indicated in Fig. 9. s .t the outer end of the spindle 31: are the semicircular members 3T which in their closed position are adapted to` be inserted in the cylinder 38, and said members are pref- `erably formed of spaced ribs 39 to provide a light skeleton construction which canbe easili7 manipulated by hand if desired.

Fnitending from the outside of the furnace to' theinner space L1 are the channels 410. n'tlie inner face of one ofthe channeled() y are the lugs 41 which form a bearing for the rock-shaft 42 extending from one end of the said channel to the other. 'A lever 43 is connected tok the outer end of said shaft. Arms 44 are rigidly mounted on said shaft, the opposite ends of said arms being connected to the bars 45 Vby a slot and pin con- Y nection 4G, as clearly indicated in Fig. 2.

The bars 45 are connected at their ends to the toggle-arms 47, the opposite ends of said togglearms being connected to the channels 4() and to the frames 48, which are slidable lvertically in the guides 49. Rack-bars are carried by frames 4S. Divided pinions 51 are mounted on each end of the divided shaft 52. This shaft 52 also carries the flattening member 53 which consists of a divided cylinder, as illustrated in Fig. 7, the working faces of said cylinder presenting a solid circular face, and formed of a suitable refractory material mounted on an inner shell is clearly illustrated in Fig. 4, the shaft 52 passes through the openings in the inner and outer furnace walls and suilicient clearance is provided for the vertical movement of said shaft as will more fully hereinafter appear.

To provide for the oscillating movement of the flattening cylinder halves, I have illustrated the following mechanism, although it is apparent that other forms of mechanism may be employed for accomplishing the same results. In this instance, I employ the lazy-tongs 56 one end of which is connected to one of the pinion halves 51 and the other to the opposite one, as clearly indicated in Fig. 2. The lazy-tongs have Y the sleeves 57 which slide up and down on theguide-rod 58. The upper of the sleeves 57V is connected to the piston-rod 59 ofthe cylinder G0. which is carried by the frame 61. It will be apparent that by the reciprocation of the piston-rod 59 the pinion-halves 51 will oscillate back and forth on the rack 50. as indicated in Fig. 2,.and this will cause a like oscillating move-ment of the halves of the flattening cylinder 53.

In practising my invention, the cylinder to v be flattened having been slit longitudinally,

as indicated in Fig. 8, is inserted in the opening l1 of the vestibule 10 of the furnace and rests upon a suitable support. The operator then advances the spindle :E4-by grasping the handles 35 and moves the semi-circular halves 37 in their closed position into the cylinder in the vestibule 10, as indicated by dotted lines Fig. 1. The spindle is then swung around and with it the beam 19 with Vthe roller 25 traveling on the track 26, until as not to drag'thereon', due to the fact that the track 27 is slightly raised, and when the cylinder has been swung around into positionV where the cylinder is supported' on one of the carriages 7, the wheel 25 travels down the lower section 27 of the track and brings the cylinder down into contact with the flattening stone of the carriage. Then this has been done the parts assume the position indicated in full lines Fig. 1, and the operator now unlocks the handles 35 by throwing back the latch 36, whereupon by separating the handlesV the halves of the spindle 34 as well as the halves 37 of the preliminaryopening member assumes the positions indicated in dotted lines Fig. 8, so that the glass cylinder is opened out on the stone 8. This operation is repeated by moving the handles back and forth to get the oscillating movement and when the glass has been Vopened out to the pro-per extent, the operator withdraws the spindle from the furnace, and swings it around in position withreference to the vestibule 10 to be inserted in a fresh cylinder which has been chargedthrough the opening 1 1. Power is nowapplied to move the carriages 7 in the furnace, and the carriage carrying the glass, which has just been opened, is moved around into position for flattening, where the carriage is stopped and the flattening operationk takes place. In

order to raise the fiatteningvcylinder 53 sulfi- This permits the glass to pass under the cylinder, whereupon the lever 43 is moved to lower the flattening cylinder onto the glass. Power is now applied tok the cylinder 60 to reciprocate the piston-rod 59 .and through the connections described, `an oscillating movement is imparted to the halves of the flattening cylinder 53 so that they move over the surface of the glass on the flattening stone and flatten it out and smooth it at the same time. This operation is continued until'the glass has been flattened, whereupon, power is applied to move the. carriages and the fiattened plate is moved beyond the flattening roll, while another plate previously opened, is brought into position to be flattened.

In the claims I wish to claim broadly the cylindrical member divided longitudinally into two parts, whether used as a preliminary opener like thecylinder 37, or whether used for the final flattening operation like the cylinder 53. It is possible that the opening and flattening may be done entirely by one cylinder.

What I claim is: Y

1. A device of the character described, comprising a member divided longitudinally,

iso

and having two curved rocking working faces. Y

2. A device of the character described, comprising a cylindrical member divided longitudinally into two rocking parts.

3. A device of the character described, comprising a member divided longitudinally into two parts having curved working faces, and means for rocking said parts on their curved faces. Y

4. A device of the character described, comprising a longitudinally divided spindle or shaft, having curved working faces on each half, and means for rocking said halves on their curved faces.

5.V A device of the character described, comprising a longitudinally divided shaft having curved working faces, means for rocking said shaft halves on their curved faces, and means for elevating said shaft.

6. In apparatus of the character described, comprising a longitudinally divided shaft having curved working faces, pinion-sections carried by said shaft-sections, a rack bar engaged by said pinion-sections, and means for oscillating said pinion-sections.

7. In apparatus of the character described, comprising a longitudinally divided shaft having curved working faces, pinion-sections carried by said shaft-sections, a rack-bar eni gaged by said pinion-sections, a power operated cylinder, and connections between said cylinder and said pinion-sections for oscillating same.

8. In apparatus of the character described, comprising a longitudinally divided shaft having curved working faces, pinion-sections carried by said shaft, a rack engaged by said pinion-section, lazy tongs engaged by said pinion-sections, and means for operating said lazy-tongs.

In testimony whereof, I, the said GEORGE C. Dnal` Y, have hereunto set my hand.
